Bandwidth usage of access networks (or the last mile) continues to grow as service providers are migrating to all IP services (IP Video, 4K Video, and other business services). Traffic from on-demand services also continues to skyrocket while total Internet usage increases 50 percent year over year. The steep increase in bandwidth demand is motivating cable operators around the world to migrate their access Hybrid Fiber COAX (HFC) network to a Distributed Access Architecture (DAA);doing so allows them to better compete with other fiber-based or over-the-top (OTT) service providers who already offer high-speed services that many of today’s existing HFC-based networks can’t support. Traditional methods of increasing bandwidth over HFC, such as adding Quadrature Amplitude Modulation (QAM), moving channels to DOCSIS, splitting nodes and other methods, will not be tenable in the near future.

MVNOs…the term is so 1990s, right? Think again. Mobile virtual network operators have been around for nearly 20 years, and there’s a reason for that—they’ve found success in both niche and broad markets, in virtually every country in the world. Recent research published by Allied Market Research forecasts that the global market was valued $52 billion in 2016, and is projected to double, reaching nearly $103 billion, by 2023, growing at a CAGR of 10.6% from 2017 to 2023. In the United States alone, more than 100 MVNOs serve the market, utilizing the networks of AT&T, Sprint, T-Mobile, Verizon, BCE, Rogers and Telus to offer varying levels of service.

2017 is becoming the year of software-defined networking (SDN) and network function virtualization (NFV). Boosted by early adoption from carriers such as AT&T, communications service providers (CSPs) are beginning to ramp investments in the NFV and SDN ecosystems to the tune of $158 billion by 2021, according to research firm Technology Business Research. The move to a more virtualized, cloud-based network architecture is seen by some as the first layer of the Digital Transformation, where a more open, flexible architecture includes tools such as data analytics and automation.
Boosted by early adoption from carriers such as AT&T, Telefónica and China Mobile, communications service providers (CSPs) are beginning to ramp up their investments in NFV/SDN initiatives. The market has seen its fair share of ups and downs, but now seems to be moving more consistently. For example, in February, AT&T announced its plans to virtualize 55% of its network to software by the end of the year, with 34% already converted to SDN by the end of 2016. The 2020 goal: 75%.

It has been 25 years since Bruce Springsteen bemoaned the fact that although he had both cable and satellite television services, he also had “57 channels and nothin’ on.” For decades, communications service providers of all types – wireless operators, wireline operators, cable MSOs and others – have been telling consumer and business customers that more is better: more channels, more minutes, more data. But the push for more recently has been a “more” of a different sort: more personalized.
